I'm attempting to go to Boost 1.28 on our HPUX 10.20 boxes. I've run into a problem with an assumption about the type of pthread_mutexattr_t. detail\lwm_pthreads.hpp calls: pthread_mutex_init(&m_, 0); HP's pthread.h (10.20 uses DCE) has that defined as: int pthread_mutex_init (pthread_mutex_t *,pthread_mutexattr_t); after tracing the typedef's down to <dce/cma.h>, I found pthread_mutexattr_t is this: typedef struct CMA_T_HANDLE { cma_t_address field1; short int field2; short int field3; } cma_t_handle; where cma_t_address is a void*. The error message is: .../boost/detail/lwm_pthreads.hpp: In method `boost::detail::lightweight_mutex::lightweight_mutex()': .../boost/detail/lwm_pthreads.hpp:40: conversion from `int' to non-scalar type `CMA_T_HANDLE' requested I'm not sure what solution to use here. Ifdefs are troublesome because it is hard to distinguish between HP 10.x and 11.x, which use different threading models. I don't know a lot about threads on HP, we use ACE so that we don't have to. One thing I do remember is that they conform to a fairly old revision of POSIX. I think attachments are prohibited on this list, so I will append pthread.h and dce/cma.h below.
